the one thing i cannot understand is why it hurts when i walk in the morning. i try to sleep with firm pillows between my legs but it doesn't help. i think it would be better too if my bed wasn't so high up. but i also been working almost 40+ hours past 2 weeks. any other mommies experience this?? i don't even have to sit long and it hurts when i get right back up.
